What is my best option to have an access about the address of my daughter?

In Utah you are definitely entitled to know where your child is during visitation. You will probably have to take him back to court for contempt for failing and/or refusing to provide that information.

He should provide the information of where the child is and a contact number.

What does your order say? If it says that he has to give you the address where he takes your daughter, then you tell him that you will move to have him held in contempt unless he tells you. If the order does not provide that, tell you will do it anyway. It may shake him up enough to tell you.

Look to your divorce decree to see if he is under any obligation to notify you of the address for your daughter is staying when he is with her. If the decree is silent on this subject (and it usually isn't), then it should be relatively easy for you to find out where your ex-husband and his wife live respectively. How? There are several ways. If you have your ex-husband's name and the name of his current wife, try doing an Internet search by their names and the cities where they live (I assume you know the city in which they live). If you can't find their addresses by using the free services available to you online, you can often pay a few dollars to get access to private databases that may have more specific information. If the online option bears no fruit, you can hire a private investigator to track down your ex-husband's address and that of his wife. If that doesn't work, you may just want to do a little private sluething of your own and follow your ex-husband's car the next time he drives away from your house when he picks up your daughter for his parent time.
